A portable cooler consists of a sheet-steel liner of mass 0.75 kg at 17.5 °C insulated on the outside.The cooler holds 1.5 liters of water at 17.5 °C. A block of ice of mass 0.18 kg and at -5 °C is placed in the cooler. Calculate the equilibrium temperature, neglecting external heat exchanges. Specific heat of sheet-steel 0.46 kJ/kg K Specific heat of Water 4. 19 kJ/kg K - Specific heat of Ice 2.04 kJ/kg K Latent heat of fusion 335 kJ/kg
